A naked man who was shot and killed by Fremont police after he refused to drop a knife while chasing his estranged wife was identified Tuesday as 37-year-old Dejuan Eaton of San Jose.

The incident began about 11 p.m. Sunday when a woman called police to report that her roommate was being attacked by Eaton, the roommate's estranged husband, at an apartment on the 4500 block of Central Avenue, said Geneva Bosques, a spokeswoman for the Fremont Police Department.

When two officers arrived, they saw a woman running from the apartment and being chased by Eaton, who was naked and armed with a knife, Bosques said.

The officers demanded that the suspect drop the knife, but he refused, prompting them to open fire, Bosques said. Eaton died at a local hospital.

The names of the officers were not released. They are on paid administrative leave, which is routine, pending investigations by police and the Alameda County district attorney's office.
